I saw the stress-ng.zombie has very unstable result. I expect around 20% regression.

After several round of profiling and testing, my understanding is fixed to the filemap_map_folio_range()
is not suitable for order-0 folio.

So I made following change to split the order-0 folio handling out instread of leave to
filemap_map_folio_range(). And all the regressions here are gone (commit 2334949153 is with the patch below):

Hi Matthew,
I am not sure whether it's worthy to add filemap_map_one_folio() to handle order-0 folio here.
But it does fix all regressions LKP reported.

I also compared the code generated for these two functions:
  - The code size of filemap_map_folio_range() is 126 bytes larger than filemap_map_one_folio()
  - There is loop in filemap_map_folio_range()


The changes of 2334949153c5e312b6f6c1f4852 is as following:
